About this tag
CWE-502, or Deserialization of Untrusted Data, is a software weakness that appears frequently in industrial control system (ICS) advisories from CISA and vendors like Siemens, Schneider Electric, Fuji Electric, and Delta Electronics. On WindowsForum, discussions cover real-world vulnerabilities such as CVE-2025-9365 in Fuji FRENIC-Loader 4, CVE-2025-40759 in Siemens TIA Portal, and flaws in Schneider EcoStruxure PME and Delta DTM Soft. These threads explain how attackers can exploit deserialization to execute arbitrary code by tricking operators into opening malicious project files. The content emphasizes patching, network hardening, and the importance of treating untrusted data carefully in engineering software.
